13.2.8 Relations limit switches/Offsets/ETSL and reference positions (summary)
Figure 23 (below) illustrates the lower final limit switch, the lower pre-triggered stopping limit, the lower inspec-
tion limit and the distance s for ETSL-calculation when moving down related to the lower (limit switch-) reference
position.
